How to calculate the RTP time stamp for each packet in the audio stream

I read the RTP specification, and I can't seem to cheat on the RTP packet timestamp. I tried to implement it differently on my server, but I can not get the player to play correctly.

The “wrong” behavior I encountered is that (I am using a VLC player to play the RTSP URL on my server). I find that the player’s logs say that the “buffer path is too late” and “the PTS value is incorrect . This means that the audio frames come in packets whose timestamp is not set correctly. I tried to generate a timestamp differently, but such there was no luck.

I need some detailed resource or link that really puts me on the right track to understand how the RTP timestamp works and is generated.
